1. The ratio of girls to boys to parents at the concert is 10:5:4. If there are 1083 people at the concert, how many parents are there?

2. Solve for x:

x - 107=x + 189

3. Solve for x:Follow steps: 1. Distribute 2. Anything not a fraction, put it over one 3. Find common denominators 4. Anything you do to the bottom, you must do to the
Top. 5. Eliminate denominators. 6. Solve

27(x - 2) + 5x = 12x - 9

4. Solve for x and state the solution(s).

-4(x - 8) - 3x = -7x + 32

1.   228 parents

Step-by-step explanation:

I will do number 1 for you.  I'll let you or someone else do the others.

Let 10x = no. of girls

      5x = no. of boys

      4x = no. of parents

Now, 10x + 5x + 4x = 1083

                        19x = 1083

                            x = 57

(10)(57) = 570 girls

(5)(57) = 285 boys

(4)(57) = 228 parents

             1083  total

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
